Well, looking back through the WebDAV mailing list archives, it doesn't look
like the Internet Draft, "Proposed Extensions for WebDAV Properties",
<draft-ietf-webdav-properties-extension-00>, was ever announced to the
mailing list.
For the record, the I-D is written by Jim Amsden, and describes three minor
extensions to the current properties protocol: 1) allow PROPPATCH to create
and initialize the properties of a resource that did not exist, 2)
distinguish between adding a new property, and setting the value of an
existing property of a resource, and 3) give client applications more
control in specifying how PROPPATCH errors should be handled.
The document is available at:

tension-00.txt
It's also available via the WebDAV WG home page, at:

I look forward to your comments on this proposal.
